Lucia, different clinics work differently. I'm in a similar position to you - I do natural FETs with no luteal phase support, I've had one pregnancy (later lost at 9 weeks), 2 chemical pregnancies (full pregnancy symptoms, AF arrived on time, trace amounts of HCG present) and one flat out BFN. My acupuncturist believes that I may have a progesterone issue - particularly because I tend to spot for a few days before AF starts on the chemical pregnancies.
It's one of the reasons I'm heading back to see my FS before we do another transfer. I've had no testing to check just what my P4 levels are like post-ovulation, though.
